This disclosure relates to an electronic apparatus and a control method thereof and, more particularly, to an electronic apparatus capable of generating tag information based on a user voice and a control method thereof.

BACKGROUND ART

In recent years, artificial intelligence (AI) systems have been used in various fields. An AI system is a system in which a machine learns, judges, and iteratively improves analysis and decision making, unlike an existing rule-based smart system. As the use of AI systems increases, for example, an accuracy, a recognition rate and understanding or anticipation of a user's taste may be correspondingly increased. As such, existing rule-based smart systems are gradually being replaced by deep learning-based AI systems.

AI technology is composed of machine learning, for example deep learning, and elementary technologies that utilize machine learning.

Machine learning is an algorithmic technology that is capable of classifying or learning characteristics of input data. Element technology is a technology that simulates functions, such as recognition and judgment of a human brain, using machine learning algorithms, such as deep learning. Machine learning is composed of technical fields such as linguistic understanding, visual understanding, reasoning, prediction, knowledge representation, motion control, or the like.

Various fields implementing AI technology may include the following. Linguistic understanding is a technology for recognizing, applying, and/or processing human language or characters and includes natural language processing, machine translation, dialogue system, question and answer, voice recognition or synthesis, and the like. Visual understanding is a technique for recognizing and processing objects as human vision, including object recognition, object tracking, image search, human recognition, scene understanding, spatial understanding, image enhancement, and the like. Inference prediction is a technique for judging and logically inferring and predicting information, including knowledge-based and probability-based inference, optimization prediction, preference-based planning, recommendation, or the like. Knowledge representation is a technology for automating human experience information into knowledge data, including knowledge building (data generation or classification), knowledge management (data utilization), or the like. Motion control is a technique for controlling the autonomous running of the vehicle and the motion of the robot, including motion control (navigation, collision, driving), operation control (behavior control), or the like.

For efficient management of information and various user experiences, electronic apparatuses have provided a function to generate tag information for an image. Tag information is data for an image and a kind of metadata.

As for the related-art tag information generation method, it is general that the tag information is generated uniformly only with information that may be identified in the same manner by anyone from an image, and a unique thinking, feeling, or the like, of a user associated with an image is not reflected as tag information.

The disclosure relates to an art for tagging information in an image, and more particularly, to generating tag information for an object included in an image more easily based on a voice (or speech). Tag information refers to data for image as a kind of metadata.

FIG. 1 is a use diagram of an electronic apparatus 100 to tag information to an image according to an embodiment.

Referring to FIG. 1 , the electronic apparatus 100 may display an image 10 that includes at least one object, and information included in the user voice may be tagged to the object included in the image 10. Here, the object may be any of a person, an object, or the like, which is present in a distinguishable manner from others. The object may be referred to as an entity.

The user may give a voice describing about the image 10 while the image 10 is being displayed in the electronic apparatus 100. The user voice describing the image 10 may be input through a microphone provided in the electronic apparatus 100. Alternatively, the user voice may be input through an external microphone electrically connected to the electronic apparatus 100.

An object associated with a voice of the objects included in the image 10, that is, a target object to be tagged with information, may be identified. The voice may include at least one description for identifying a target object to be tagged with information. For example, the voice may include at least one of a description of an appearance of the target object, a description of a gender of the target object, a description of a color of the target object, a description of a position of the target object, a description of a category of the target object, a description of a name of the target object, or the like. According to an embodiment, the target object in an image may be identified by inputting a voice and an image to an artificial intelligence (AI) model trained by an AI algorithm.

In an example of FIG. 1 , the target object 11 may be identified in the image 10 based on a voice that “the left is my son, Junseo.”

When an object related to a voice is identified, the electronic apparatus 100 may display a user interface (UI) element notifying that the identified object is the target object to be tagged. For example, as illustrated in FIG. 1 , the electronic apparatus 100 may display a rectangular UI element surrounding the target object 11 to be tagged.

Tag information 12 for the target object 11 may be obtained based on the voice. In FIG. 1 , the words included in the voice, “son” and “Junseo”, are tagged to the target object 11. According to an embodiment, a voice is input to an AI model trained by an AI algorithm to obtain a keyword from the voice, and the obtained keyword may be tagged to the target object. The electronic apparatus 100 may display the tagged keywords with the image 10.

The keyword of the input user voice subsequently input may be additionally tagged to the target object 11. Referring to the embodiment of FIG. 1 , “5 years” and “little rascal” are additionally tagged. The tag information 12 may be displayed with the image 10. As illustrated in FIG. 1 , a keyword of the voice subsequently input is added as the tag information and may be displayed together with the keyword previously displayed.

FIG. 2 is a block diagram illustrating a configuration of the electronic apparatus 100 according to an embodiment.

Referring to FIG. 2 , the electronic apparatus 100 includes a display 110, a memory 120, a microphone 130, and a processor 140. According to an implementation type, some configurations may be omitted, and some hardware/software configurations which are not illustrated but are obvious to those skilled in the art may be additionally included in the electronic apparatus 100.

The display 110 may include, for example, a liquid crystal display (LCD), light-emitting diode (LED) display, an organic light-emitting diode (OLED), a display (for example, active-matrix organic light-emitting diode (AMOLED), passive-matrix OLED (PMOLED)), or a microelectromechanical systems (MEMS) display, or an electronic paper display.

The display 110 may display various images, for example, images including texts, images, videos, icons, or symbols.

According to an embodiment, the display 110 may include a touch screen and may receive a touch, a gesture, proximity, or hovering input using, for example, an electronic pen or a part of the user's body.

The memory 120 may, for example, include an embedded memory or an external memory. The embedded memory may, for example, include at least one of a volatile memory (e.g. dynamic random access memory (DRAM)), a static RAM, a synchronous dynamic RAM (SDRAM), a non-volatile memory (e.g. one time programmable read only memory (OTPROM)), a programmable ROM (PROM), an erasable and programmable ROM (EPROM), an electrically erasable and programmable ROM (EEPROM), a mask ROM, a flash ROM, a flash memory (e.g. NAND flash or NOR flash, etc.), a hard drive, and a solid state drive (SSD).

The external memory may further include a flash drive, such as a compact flash (CF), a secure digital (SD), a micro secure digital (Micro-SD), a mini secure digital (Mini-SD), an extreme digital (xD), a multi-media card (MMC), or a memory stick. The external memory may be connected to the electronic apparatus 100 functionally and/or physically through various interfaces.

The memory 120 is accessed by the processor 140, and read/write/modify/delete/update of data by the processor 140 may be performed. The term memory in this document refers to the memory 120 (not shown), a ROM in the processor 140, a RAM, or a memory card (for example, a micro SD card and a memory stick) provided on the electronic apparatus 100. The memory 120 may store computer executable instructions. In the memory 120, a program, data, or the like, for configuring various screens to be displayed in a display region of the display 110 may be stored.

According to an embodiment, the memory 120 may be implemented with not only a storage medium inside the electronic apparatus 100 but also a web server, or the like, through network.

The microphone 130 is a structure for receiving sound. The microphone 130 may convert the received sound into an electrical signal. The microphone 130 may be implemented integrally with or separated from the electronic apparatus 100. The separated microphone 130 may be electrically connected to the electronic apparatus 100.

The processor 140 is a configuration for controlling the overall operation of the electronic apparatus 100. The processor 140 may be implemented, for example, as a central processing unit (CPU), an application specific integrated circuit (ASIC), a system on chip (SoC), a MICOM, or the like. The processor 140 may operate an operating system or an application program to control a plurality of hardware or software components connected to the processor 140, and may perform various data processing and operations. According to one embodiment, the processor 140 may further include a graphics processing unit (GPU) and/or an image signal processor. The processor 140 may execute the computer executable instructions to perform the functions according to various embodiments of the disclosure.

The processor 140 may perform various operations in association with the display 110, the memory 120, and the microphone 130, by executing a computer-executable instruction stored in the memory 120.

For example, the processor 140 may control the display 110 to display an image including at least one object. The processor 140 may identify an object related to a voice among at least one object included in an image displayed in the display 110 and generate tag information for the identified object, by inputting a user voice received through the microphone 130 to a model trained by the AI algorithm. The processor 140 may provide the generated tag information.

For example, referring to FIG. 1 , when user voice is input through the microphone 130 of the electronic apparatus 100 while the image 10 is displayed through the display 110 of the electronic apparatus 100, the processor 140 may input voice to the AI model trained by the AI algorithm to identify the object 11 associated with the voice, generate tag information 12 for the object, and provide the tag information 12 via the display 110.

The AI model trained by the AI algorithm may be stored in the memory 120. The AI model trained by the AI algorithm may be stored in a server external to the electronic apparatus 100 so that when the electronic apparatus 100 transmits the image and user voice (voice data) to the server, the external server may identify the object related to the voice in the image and transmit the result to the electronic apparatus 100.

According to an embodiment, a content of the voice of the user from a point designated by the user may be tagged to an object in the image. That is, the tagging function of the electronic apparatus 100 may be initiated at a point of time desired by the user. A variety of ways may be used to initiate the tagging function.

FIGS. 3 and 4 are views illustrating various embodiments related to executing a tagging function.

Referring to FIG. 3 , the electronic apparatus 100 according to one embodiment of may provide a UI element 20 for initiating a tagging function for the image 10, and may initiate a tagging function when the UI element 20 is selected. A tagging operation may be performed based on the input voice after the tagging function is initiated. The UI element 20 may be selected via a variety of input methods. For example, if the electronic apparatus 100 is an apparatus including a touch screen, the user may initiate the tagging function by touching the UI element 20.

FIG. 4 is a view illustrating various embodiments related to executing a tagging function based on voice recognition.

The electronic apparatus 100 may include an AI agent for providing a voice recognition server. The AI agent is a dedicated program for providing AI-based service (for example, voice recognition service, assistant service, translation service, search service, or the like), and may be executed by an existing general-purpose processor or a separate AI-dedicated processor.

For example, a tagging function may be initiated when a user utters a word (e.g., a “Bixby”) to initiate a voice recognition function and utters a voice (e.g., “Execute a tagging function”) requesting a tagging function, a tagging function may be initiated. In this example, a UI 30 indicating that the tagging function for the image 10 has been initiated may be displayed. For example, as shown in FIG. 4 , the UI 30 may include a guide phrase that guides a user to speak information to be tagged to an object in the image 10. After the tagging function is initiated by the voice, a tagging operation may be performed based on the input voice.

As described above, according to an embodiment in which a tagging operation is performed based on the voice that is input after the tagging function is initiated, there is an effect that only the words desired by a user may be tagged to an image.

According to an embodiment, a tag may be deleted during tagging via voice. For example, a UI element to delete a keyword of the voice included in the tag information may be displayed. This will be described with reference to FIG. 5 .

Referring to FIG. 5 , the electronic apparatus 100 may provide a UI element 40 for deleting by tagged words. When the user selects the UI element 40, the tag may be deleted. For example, when the UI element 40 displayed beside “son” is selected, the “son” may be deleted from the tag information.

According to another embodiment, it is possible to modify and edit tagged words. For example, if the electronic apparatus 100 has a touch screen, if the user touches, for example, “son” among the tag information displayed on the touch screen, “son” may be in a modifiable state. A cursor and a soft keyboard may be displayed in a modifiable state, and the user may modify the content using a soft keyboard. It is possible to modify, delete, and also enter a new tag content through the soft keyboard.

According to the embodiments described above, the content a user does not want to be tagged during speaking may be excluded, and there is an effect that even if voice is not correctly recognized, a tag may be modified.

When tagging is terminated, the user may terminate a tagging function. According to the disclosure, the tagging function may be terminated by various methods. FIG. 6 illustrates an embodiment of terminating the tagging function.

Referring to FIG. 6 , the electronic apparatus 100 may provide a UI 50 asking whether to terminate the tagging. For example, the electronic apparatus 100 may determine that the user is intended to finish the tagging and display a UI 50 if the user voice is not entered for a predetermined period of time during tagging. In response to the displayed UI 50, if the user speaks a consented voice, such as, for example, “Yes,” the electronic apparatus 100 may recognize this and terminate the tagging function. The electronic apparatus 100 may match the object 11 in the image 10 with the tag information 12 and store the same in the memory 120.

The tagging function may be terminated in a variety of ways. According to another embodiment, when a user speaks a voice intended for terminating tagging, such as “describing a photo ended”, “the electronic apparatus 100 may recognize it and terminate the tagging function. According to another embodiment, the electronic apparatus 100 may display an icon for terminating the tagging function along with the image 10 and may terminate the tagging function if the icon is selected.

According to an embodiment, if there are a plurality of objects with which the user wishes to tag information in an image, the user may distinguish the objects for tagging. For example, if a plurality of objects associated with a voice input from an image are identified, the electronic apparatus 100 may obtain tagging information for each of the plurality of objects based on the input voice. This embodiment will be described with reference to FIG. 7 .

FIG. 7 is a diagram illustrating an embodiment of tagging information to a plurality of objects according to an embodiment.

Referring to FIG. 7 , when tagging for Junseo is completed, the user may perform tagging for Yunseo in the image 10.

The electronic apparatus 100 may identify an object corresponding to a trigger voice when the trigger voice for object conversion is input while tagging for the first object in the image 10 is performed, and perform new tagging on the identified object. The trigger voice may include, for example, at least one of a description of the appearance of the target object, a description of the gender of the target object, a description of the color of the target object, a description of the position of the target object, a description of the category of the target object, a description of the name of the target object, or the like. As illustrated in FIG. 7 , a description of the position of an object, such as “right”, may be a trigger voice to switch the object to be tagged.

The electronic apparatus 100 may display a UI element indicating that the new object is to be tagged if a new object 13 is identified by inputting a trigger voice for object conversion. For example, as shown in FIG. 7 , a rectangular UI element surrounding the identified object 13 may be displayed. When the new object 13 is identified and user voice is input, tag information 14 for the new object 13 may be generated based on the input voice.

According to the embodiment, while the user speaks naturally, tag information for each of several objects in the image may be generated.

Identifying the target object for tagging based on the voice is described in the embodiments above, but according to still another embodiment, the target object may be identified by a user manipulation. FIG. 8 illustrates the embodiment.

Referring to FIG. 8 , when the electronic apparatus 100 has a touch screen, when a user touch with respect to the displayed image 10 is detected through the touch screen, the electronic apparatus 100 may identify an object located where the touch is detected as a target object for tagging. When the target object for tagging is identified and the user voice is input, tag information 14 for the target object 13 for tagging may be generated based on the input voice.

Identifying an object based on user manipulation, as described above, may be used as an auxiliary means when identification of an object based on voice is not successfully performed. For example, the electronic apparatus 100 may display a guide UI, such as “please touch an object to be tagged”, if the electronic apparatus 100 fails to identify the object based on voice.

According to an embodiment, tag information may be obtained with reference to pre-generated tag information. For example, the electronic apparatus 100 may identify the first object associated with a voice in an image and obtain the tag information for the first object with reference to the pre-generated tag information for a second object included in the image. An embodiment of the present invention will be described with reference to FIGS. 9 to 10 .

Referring to FIG. 9 , if pre-generated tag information 70 exists for the first object 11 among the objects in the image 10, the pre-generated tag information 70 may be referred to, when the tag information for the second object 13 is generated based on the user voice. The tag information 70 may be stored in the memory 120.

As shown in FIG. 9 , when a user voice of “older than Junseo by four years” is input, the electronic apparatus 100 may input the voice and tag information 70 to a trained AI model using an AI algorithm to obtain information from the pre-generated tag information 70 that Junseo is five years old and the target object 13 to be tagged is four years older than Junseo, and thus may tag “nine years” to a target object 13 for tagging based on the obtained information.

FIG. 10 is a diagram illustrating another embodiment associated with generating new tag information with reference to pre-generated tag information.

Referring to FIG. 10 , when there is the pre-generated tag information 80 for the first object 13 among the objects inside the image 10, the pre-generated tag information 80 may be referred to, when the tag information for a second object 15 is generated based on the user voice.

As illustrated in FIG. 10 , when the user voice, “that water gun Yunseo is playing with,” the electronic apparatus 100 may extract tag information 80 including “Yunseo” among the pre-generated tag information and generate new tag information 80 including the extracted tag information 80.

The generated tag information may be used in various ways. For example, when a user utters a voice including an intention to purchase a specific object, the electronic apparatus 100 may display a web page for purchasing the object by referring to tag information corresponding to the object. For example, in the example of FIG. 10 , when the user utters a voice saying, “Junseo is dying to have the water gun Yunseo is playing with. I need to order one for Junseo too,” the electronic apparatus 100 may refer to a named entity from the tag information 90 generated for the water gun and display a website that sells a pink water gun by referring to the named entity.

According to an embodiment, the electronic apparatus 100 may input an image to a first AI model to obtain information on at least one object in the image, and identify an object related to the voice among the obtained at least one object based on information on the at least one object and a word included in the voice. The voice may be input to a second AI model to obtain tag information including a keyword of the voice.

The tag information may include tag information obtained by analyzing an image as well as tag information obtained based on the voice. That is, for example, the tag information may include information about the identified object among information about at least one object obtained by inputting the image to the first AI model as well as the keyword of the obtained voice by inputting the voice to the second artificial intelligence model. The first AI model may be a model for visual understanding, and the second AI model may be a model for linguistic understanding.

FIG. 11 is a diagram illustrating tag information according to an embodiment.

The tag information for the object in the image may include information about the object obtained by analyzing the image. Referring to FIG. 11 , a “named entity” item is information obtained through image analysis. Various conventional image analysis techniques may be used to obtain information about an object. For example, an AI model may be used to analyze an image to recognize a category of an object (human animal, thing, landscape, etc.), and it is possible to recognize an appearance, color, gender, age, face, or the like, of the object. Through such image analysis, information on the object may be obtained and included in the tag information.

The tag information may include information on an object obtained by inputting the voice input from the user to the AI model. Referring to FIG. 11 , “attribute” item refers to information obtained through the voice.

The information obtained through the voice is reflected with a user's unique thinking, feeling, or the like, and has a property as more personalized information as compared to the information obtained through image analysis. According to an embodiment, tag information may be generated by including information obtained through image analysis and information obtained through voice, so that more various kinds of tag information may be utilized.

The tag information includes an image in which the target object for tagging is identified. Referring to FIG. 11 , “image” item is an image in which the object to be tagged is identified.

The tag information 70, 80, and 90 generated as shown above may be stored in the memory 120. The generated tag information 70 and 80 may be stored in an external server and shared with other users.

FIG. 12 is a diagram illustrating tag information generating according to an embodiment.

Referring to FIG. 12 , a user voice is input to a voice engine 1210, and an image including at least one object is input to an image engine 1220. The voice engine 1210 may perform processing on the input voice using a model for linguistic understanding trained using an AI algorithm. The image engine 1220 may perform processing on the image using a model for visual understanding trained by using an AI algorithm.

A voice input to an automatic voice recognition module (ASR) 1211 is converted to a plain text. A natural linguistic understanding (NLU) module 1212 receiving the converted text may perform several analyses for making the system understand the converted text.

Based on the converted text using the ASR module 1211, the NLU module 1212 may perform a natural linguistic understanding process to grasp the intention of the user utterance. In the natural linguistic understanding process, morpheme analysis, syntactic analysis, dialogue act, main action, keyword analysis, or the like, may be performed. Specifically, the NLU module 1212 may perform a morpheme analysis to divide a text into a unit of a morpheme that is the smallest semantic unit to analyze which word class each morpheme has. By the morpheme analysis, information of a word class such as noun, verb, adjective, postposition, or the like, may be identified. The NLU module 1212 may perform syntactic analysis processing. The syntactic analysis is performed by dividing a user's utterance with a specific reference, such as a noun phrase, a verb phrase, an adjective phrase, etc., and analyzing whether there is any relationship between each divided chunk. Through this syntactic analysis, subject, object, qualifiers of the user utterance may be grasped.

Keywords of the voice obtained as a result of analyzing the voice from the NLU module 1212 may be included as “attribute” item from tag information.

The image engine 1220 includes an object recognition engine 1221, and the object recognition engine 1221 may identify which things appear in the image. For example, the image engine 1220 may use the feature vector technique to identify what the object is. The feature vector technique is a technique in which various features of an object, such as color, shape, movement, etc., are combined to recognize what is the object. For example, if an image including a male child is input, the object recognition engine may define a male child through recognition of physique, ratio, facial feature, or the like, of the object.

The object recognition engine 1221 may provide information (for example, “male child”) on the object as a result of processing an image and this may be included in the tag information as the “named entity” item.

An agent 1240 may be an AI agent. The AI agent is a dedicated program for providing an AI-based service (e.g., a voice recognition service, an assistant service, a translation service, a search service, etc.), and may be executed by an existing general purpose processor (e.g., a central processing unit (CPU)) or a separate AI-only processor (e.g., graphics processing unit (GPU), etc.). The agent 1240 may be mounted on the electronic apparatus 100 or mounted on the external server of the electronic apparatus 100.

For an entity (for example, what is “that”, call “that person”) among the user utterance which is not understandable, the agent 1240 may distinguish by utilizing a dialogue task ontology 1230.

A tag generator 1250 may generate tag information based on information obtained through the voice engine 1210 and the image engine 1220 and store the information in database 1260.

In the above-described embodiment, at least one of the voice engine 1210, the object recognition engine 1220, the agent 1240, the dialogue task ontology 1230, and the tag generator 1250 may be implemented as a software module or in a form of at least one hardware chip and mounted to the electronic apparatus 100, or may be alternatively mounted on an external server of the electronic apparatus 100. When the voice engine 1210, the object recognition engine 1220, and the agent 1240 are implemented in a software module (or a program module including an instruction), the software module may be stored in a computer readable non-transitory computer readable media. In this example, the software module may be provided by an operating system (OS), or provided by a predetermined application. Alternatively, some of the software modules may be provided by the OS, and some of which may be provided by predetermined applications.

FIG. 13A is a diagram illustrating generating tag information according to an embodiment.

When a user (A) says “the left is my son Junseo” while looking at an image displayed on the electronic apparatus 100, the object recognition engine 1221 may identify objects in the photo, obtain feature information (e.g., gender, age, etc.) of the object through the image analysis, and obtain information on the object position in the image, the relationship of the object, the gender, the name, or the like. The tag information 75 may be generated based on the recognition information for the image and the recognition information for the voice. The tag information 75 may include various information as an attribute, such as, for example, relation, gender, age, color, or the like, depending on the recognition information.

Referring to FIG. 13B, information may be added to the tag information 75 based on an additionally input voice. In this example, abstract information (age: child) grasped by image recognition may be supplemented as detailed in formation (age: 5) through recognition information for the voice.

Database including tag information may be generated for each user, and a group including various users may share tag information of each other. For example, referring to FIG. 14 , a first user's database 1260 and a second user's database 1270 may be generated. The first user's database 1260 and the second user's database 1270 may be stored in a cloud server. Databases for tag information may be shared between designated user groups. The agent 1240 may provide various services based on the database for shared tag information. For example, users belonging to a group may have a dialogue using tag information when having a dialogue. An embodiment will be described with reference to FIG. 15 .

FIG. 15 illustrates a chatting screen displayed on the electronic apparatus 100 according to an embodiment. A UI 1300 including information on the daughter of Jaein may be displayed to a user of the electronic apparatus 100 who is not aware of the daughter of a dialogue partner Jaein.

The agent 1240 may include the NLU module 1241, a tagging action planner 1242, and a natural language generation (NLG) module 1243. The agent 1240 may be an A agent. The A agent is a dedicated program for providing an AI-based service (e.g., a voice recognition service, an assistant service, a translation service, a search service, or the like), and may be executed by an existing general purpose processor (e.g. CPU) or a separate AI-only processor (e.g., GPU). The agent 1240 may be mounted on the electronic apparatus 100 or mounted on the external server of the electronic apparatus 100.

The NLU module 1241 performs a natural linguistic understanding process on the text input to the chat screen, and based on the result, the tagging action planner 1242 may obtain tagging information 80 included in the data base 1260 of Jaein. The NLG module 1243 is a module for making the result data in a natural language form, and may generate information in a natural language form based on the tagging information 80, and the UI 1300 including the generated information may be displayed in the electronic apparatus 100.

FIG. 16 is a diagram illustrating tag information usage according to another embodiment.

Referring to FIG. 16 , when a user is interested in a specific portion of an object having tag information, a portion of the object may be enlarged and displayed, and the portion may be separately managed as an image of interest of the user. For example, as shown in FIG. 16 , if the user voices “Look at the facial expression of Junseo. He is so cute,” natural language analysis is performed through the NLU module 1212, and the tag information 75 corresponding to “Junseo” is searched ({circle around (1)}). The object 11 in the image is identified from the tag information 75 ({circle around (2)}), and the face is detected as the relevant area in the image from the word “facial expression” obtained in the NLU module 1212 ({circle around (3)}{circle around (4)}), and the object recognition engine 1221 detects a face area 11 a in the object 11 ({circle around (5)}). The detected area may be enlarged and displayed in the electronic apparatus 100 and added to the tag information 75 ({circle around (7)}{circle around (8)}). The electronic apparatus 100 may separately store the detected area in the memory 120 as an image of interest.

FIG. 17 is a view illustrating an embodiment of generating tag information for a food in a refrigerator.

The electronic apparatus 100 may be implemented as a refrigerator including a display. Images 1710 and 1720 shown in FIG. 17 is an image of the inside of the electronic apparatus 100 embodied as a refrigerator and may be displayed through a display provided on a front surface of the refrigerator. Referring to FIG. 17 , the NLU module 1212 may identify the meaning of the “what is input now” during the utterance of the user (Jaein), and the object recognition engine 1221 may compare the current image 1720 with the previous image 1710 before the event that the refrigerator door is opened and closed to identify newly added objects 1721 and 1722. Based on the information obtained by analyzing the user's utterance by the NLU module 1212, the object recognition engine 1221 may recognize the position of the objects 1721 and 1722 in the current image 1721. Tag information 1721 a and 1722 b for each of the objects 1721, 1722 may be generated based on information about what the objects 1721, 1722 are (e.g., food type), when the objects 1721, 1722 are created (e.g., create time).

As described above, tag information for foods included in an image of the electronic apparatus 100 embodied in a refrigerator may be generated, and the generated tag information may be stored in a database of a user (Jaein). The tag information may then be provided to Sera who is allowed to share the tag information. The embodiment will be described with reference to FIG. 18 .

Referring to FIG. 18 , looking at the image 1810 capturing the inside of a refrigerator, if another user (Sera) utters a voice, “which young radish kimchi is made by Jaein?”, the NLU module 1212 may analyze the meaning, and the tagging action planner 1242 may obtain information on a position of the object based on the voice recognition result and the tag information 1722 b of the database of Jaein. Based on the obtained information, the agent 1240 may output a voice guide, such as “let me show you a position of storage in a refrigerator” along with an image 1820 including a graphical object (a rectangle surrounding the object) for identifying the position of the object. The agent may be mounted on the electronic apparatus 100 embodied in a refrigerator, mounted on a mobile terminal device (e.g., a smartphone), or another separate agent.

The embodiments described above may be implemented by using artificial intelligence (AI) systems. The AI systems are computer systems that implement human-level intelligence in which the machine learns, determines and becomes smart, and the more the AI systems are used, the more the recognition rate is improved.

AI technology may be composed of a technology that learns a model using an AI algorithm that classifies/learns the characteristics of input data by itself and a technology that simulates functions such as recognition and determination of human brain using trained model.

Examples of the trained model include a model for linguistic understanding for recognizing human language/characters, a model for visual understanding for recognizing objects as human vision, a model for inference/prediction for judging and logically inferring and predicting information, and a model for knowledge representation for processing human experience information into knowledge data, or the like.

According to an embodiment, human language and characters may be recognized, applied, and processed using the linguistic understanding model. Relevant functions include natural language processing, machine translation, dialogue system, question/answer, voice recognition/synthesis, or the like.

According to an embodiment, using visual understanding model, recognition of an object in an image, object tracking, image search, human recognition, scene understanding, spatial understanding, or the like, may be performed.

According to an embodiment, using inference/prediction model, knowledge/probability based inference, optimization prediction, preference-based planning, and recommendation, or the like, may be performed.

According to an embodiment, using knowledge representation model, knowledge building (data generation/classification) and knowledge management (data utilization), or the like, may be performed.

According to an embodiment, a new model may be generated and used based on two or more of the various models above.

The learned (or trained) model is a learned determination model based on an artificial intelligence (AI) algorithm, for example, it may be a model based on a neural network. The learned AI model may include a plurality of weighted network nodes that may be designed to simulate the human brain structure on a computer and simulate a neuron of a human neural network. The plurality of network nodes may each establish a connection relationship so that the neurons simulate the synaptic activity of the neurons sending and receiving signals through the synapse. Also, the learned AI model may include, for example, a neural network model or a deep learning model developed from a neural network model. In the deep learning model, a plurality of network nodes are located at different depths (or layers), and may transmit and receive data according to a convolution connection relationship. Examples of learned AI models include, but are not limited to, Deep Neural Network (DNN), Recurrent Neural Network (RNN), and Bidirectional Recurrent Deep Neural Network (BRDNN).

Various embodiments may use a personal assistant program that is an AI-dedicated program (or AI agent). The personal assistant program is a dedicated program to provide AI-based service and may be executed by an existing general-purpose processor (e.g., CPU) or separate AI-exclusive processor (e.g., GPU, or the like).

When a predetermined user input (e.g., an icon touch corresponding to a personal assistant chatbot, a user voice including a preset word, or the like) is input or a button (e.g., a button for executing an AI agent) provided in the electronic apparatus 100 is pressed, an AI agent mounted on the electronic apparatus 100 may be operate (or executed). The AI agent may transmit information on the voice of a user and information on an image including the target object to be tagged to an external server, and may provide tagging information based on the data received from the external server.

The AI agent may be previously executed before a predetermined user input is detected or a button provided in the electronic apparatus 100 is selected. In this example, when the tagging function is executed, the AI agent of the electronic apparatus 100 may obtain tagging information based on the image and the user voice. The AI agent may be in a standby state before a predetermined user input is detected or a button provided in the electronic apparatus 100 is selected. Here, the standby state is a state in which a predefined user input is detected to control the start of operation of the AI agent. When the tagging function is executed while the AI agent is in a standby state, the electronic apparatus 100 may operate the AI agent and obtain tagging information based on the image and the user voice.

The above-described embodiments may be implemented using an AI model in a server external to the electronic apparatus 100, or the electronic apparatus 100 may directly use the AI model. In this example, the AI agent mounted on the electronic apparatus 100 may control the AI model to perform the operations of the above-described embodiments.

FIG. 19 is a block diagram illustrating a processor for learning and using a recognition model according to an embodiment.

Referring to FIG. 19 , a processor 1500 may include at least one of a learning unit 1510 and an analysis unit 1520.

The learning unit 1510 may generate or train an artificial intelligence model using learning data.

For example, the learning unit 1510 may generate, train, or update a model for linguistic understanding by using human language as learning data.

As a still another example, the learning unit 1510 may generate, train, or update a visual understanding model using an image including at least one object as learning data.

As another example, the learning unit 1510 may generate, train, or update a model for object recognition that recognizes (or identifies) an object referred to by a human language refers an image using an image including a human language and at least one object as learning data. The model for object recognition may be generated, trained or updated separately, or may be generated, trained or updated based on a model for linguistic understanding and a model for visual understanding.

The analysis unit 1520 may perform linguistic understanding, visual understanding, object recognition, or the like, by using the predetermined data as input data to a trained model.

For example, the analysis unit 1520 may identify an intention of a user appearing in the voice by using the voice as input data to the linguistic understanding model.

When functionally divided, the linguistic understanding model may include the ASR module. NLU module, and NLG module. The ASR module, NLU module, and NLG module have been described above and thus will not be further described.

As another example, the analysis unit 1520 may obtain (or estimate, infer) information about the at least one object using an image including at least one object as input data in a model for visual understanding. For example, if the image 10 shown in FIG. 1 is used as input data in a model for visual understanding, two of the objects that are classified into humans are detected, and that one is a boy and one is a girl may be obtained.

As another example, the analysis unit 1520 may recognize an object which the user voice in the image refers to with an image including user voice and at least one object as input data for a model for object recognition. Alternatively, the analysis unit 1520 may recognize an object which the user voice in the image refers to using information obtained through the model for linguistic understanding and the model for visual understanding as input data.

For example, at least a portion of the learning unit 1510 and at least a portion of the analysis unit 1520 may be implemented as software modules or at least one hardware chip form and mounted in the electronic apparatus 100. For example, at least one of the learning unit 1510 and the analysis unit 1520 may be manufactured in the form of an exclusive-use hardware chip for artificial intelligence (AI), or a conventional general purpose processor (e.g., a CPU or an application processor) or a graphics-only processor (e.g., a GPU) and may be mounted on various electronic apparatuses as described above. Herein, the exclusive-use hardware chip for artificial intelligence is a dedicated processor for probability calculation, and it has higher parallel processing performance than existing general purpose processor, so it can quickly process computation tasks in artificial intelligence such as machine learning. When the learning unit 1510 and the analysis unit 1520 are implemented as a software module (or a program module including an instruction), the software module may be stored in a computer-readable non-transitory computer readable media. In this case, the software module may be provided by an operating system (OS) or by a predetermined application. Alternatively, some of the software modules may be provided by an O/S, and some of the software modules may be provided by a predetermined application.

The learning unit 1510 and the analysis unit 1520 may be mounted on one electronic apparatus, or may be mounted on separate electronic apparatuses, respectively. For example, the processor 1500 of FIG. 19 may be a processor 140 of FIG. 2 . For example, one of the learning unit 1510 and the analysis unit 1520 may be implemented in the electronic apparatus 100, and the other one may be implemented in an external server. In addition, the learning unit 1510 and the analysis unit 1520 may provide the model information constructed by the learning unit 1510 to the analysis unit 1520 via wired or wireless communication, and provide data which is input to the analysis unit 1520 to the learning unit 1510 as additional data.

FIG. 20 is a block diagram illustrating a learning unit 1510 according to an embodiment.

Referring to FIG. 20 , the learning unit 1510 according to some embodiments may implement a learning data acquisition unit 1510-1 and a model learning unit 1510-4. The learning unit 1510 may further selectively implement at least one of a learning data preprocessor 1510-2, a learning data selection unit 1510-3, and a model evaluation unit 1510-5.

The learning data acquisition unit 1510-1 may obtain learning data for training models for linguistic understanding, visual understanding, object recognition, or the like. The learning data may be data collected or tested by the learning unit 1510 or a manufacturer of the learning unit 1510. For example, the learning data may include an image that includes voice, at least one object.

The model learning unit 1510-4 may use the learning data to train a model to have a reference about how to understand, recognize, determine, infer, or the like, the input data. For example, the model learning unit 1510-4 may extract a feature from the input image, project the feature into a vector space, and index the information of the object in each vector to construct a model for visual understanding.

The model learning unit 1510-4 may train a model through supervised learning of at least a part of the learning data. Alternatively, the model learning unit 1510-4 may learn, for example, by itself using learning data without specific guidance to make the artificial intelligence model learn through unsupervised learning which detects a criterion for determination of a situation. Also, the model learning unit 1510-4 may train the model through reinforcement learning using, for example, feedback on whether the result of providing the response according to learning is correct. The model learning unit 1510-4 may also make the model learn using, for example, a learning algorithm including an error back-propagation method or a gradient descent.

In addition, the model learning unit 1510-4 may learn a selection criterion about which learning data should be used for estimating a target of recognition using input data.

The model learning unit 1510-4 may determine a model having a great relevance between the input learning data and the basic learning data as a model to be learned when there are a plurality of models previously constructed. In this case, the basic learning data may be pre-classified according to the type of data, and the model may be pre-constructed for each type of data. For example, the basic learning data may be pre-classified into various criteria such as a region in which the learning data is generated, the time at which the learning data is generated, the size of the learning data, the genre of the learning data, the creator of the learning data, the type of the object in the learning data, or the like.

When the model is trained, the model learning unit 1510-4 may store the trained model. For example, the model learning unit 1510-4 may store the trained model in the memory 120 of the electronic apparatus 100. Alternatively, the model learning unit 1510-4 may store the trained model in a memory of a server connected to the electronic apparatus 100 via a wired or wireless network.

The learning unit 1510 may further implement a learning data preprocessor 1510-2 and a learning data selection unit 1510-3 to improve the processing capability of the model or to save resources or time required for generation of the model.

The learning data preprocessor 1510-2 may preprocess obtained data so that the data obtained in the learning for determining the situation may be used. The learning data preprocessor 1510-2 may process the obtained data into a predetermined format so that the model learning unit 1510-4 may use the obtained data for learning for the determination of a situation.

The learning data selection unit 1510-3 may select data required for learning from the data obtained by the learning data acquisition unit 1510-1 or the data preprocessed by the learning data preprocessor 1510-2. The selected learning data may be provided to the model learning unit 1510-4. The learning data selection unit 1510-3 may select learning data necessary for learning from the obtained or preprocessed data in accordance with a predetermined selection criterion. The learning data selection unit 1510-3 may also select learning data according to a predetermined selection criterion by learning by the model learning unit 15104.

The learning unit 1510 may further include the model evaluation unit 1510-5 to improve a processing ability of the model.

The model evaluation unit 1510-5 may input evaluation data to the model, and if the result which is output from the evaluation data does not satisfy a predetermined criterion, the model evaluation unit 1510-5 may make the model learning unit 1510-4 learn again. In this example, the evaluation data may be predefined data to evaluate the model.

For example, the model evaluation unit 1510-5 may evaluate, among the analysis results of the trained model for the evaluation data, that the analysis result does not satisfy a predetermined criterion when the number or ratio of the evaluation data of which analysis result is not correct exceeds a preset threshold.

When there are a plurality of trained models, the model evaluation unit 1510-5 may evaluate whether each trained model satisfies a predetermined criterion, and determine the model which satisfies a predetermined criterion as a final model. Here, when there are a plurality of models that satisfy a predetermined criterion, the model evaluation unit 1510-5 may determine one or a predetermined number of models which are set in an order of higher evaluation score as a final model.

Referring to FIG. 21 , the analysis unit 1220 according to some embodiments may include the input data acquisition unit 1520-1 and the analysis result provision unit 1520-4. The analysis unit 1520 may further include at least one of a data preprocessor 1520-2, a data selection unit 1520-3, and a model update unit 1520-5 in a selective manner.

The data acquisition unit 1520-1 may obtain data necessary for analysis. The analysis result provision unit 1520-4 may provide a result which is obtained by inputting the data obtained from the data acquisition unit 1520-1 to the trained model. The analysis result provision unit 1520-4 may provide an analysis result in accordance with a purpose of data analysis. The analysis result provision unit 1520-4 applies the data selected by the data preprocessor 1520-2 or the data selection unit 1520-3 to be described later to the model as an input value to obtain the response result. The response result may be determined by the model.

In an embodiment, the analysis result provision unit 1520-4 may obtain (or estimate) information for each object by applying an image including at least one object obtained from the data acquisition unit 1520-1 to a trained model for visual understanding.

In another embodiment, the analysis result provision unit 15204 may apply an image including at least one object and the voice obtained from the data acquisition unit 1520-1 to a trained model for object recognition to recognize (or identify) an object indicated by the voice.

As another embodiment, the analysis result provision unit 1520-4 may determine a user's intention corresponding to the voice by applying voice (voice data) obtained from the data acquisition unit 1520-1 to a trained model for linguistic understanding.

The analysis unit 1520 may further include the data preprocessor 1520-2 and the data selection unit 1520-3 in order to improve an analysis result of the model or save resources or time to provide the analysis result.

The input data preprocessor 1520-2 may preprocess the obtained data so that the obtained data may be used to determine a situation. The data preprocessor 1520-2 may process the obtained data into the pre-defined format by the analysis result provision unit 1520-4.

The data selection unit 1520-3 may select data required for determining a situation from the data acquired by the data acquisition unit 1520-1 or the data preprocessed by the input data preprocessor 1520-2. The selected data may be provided to the analysis result provision unit 15204. The data selection unit 1520-3 can select some or all of the obtained or preprocessed data according to a predetermined selection criterion for determining a situation. The data selection unit 1520-3 can also select data according to a predetermined selection criterion by learning by the model learning unit 1510-4.

The model update unit 1520-5 may control the updating of the model based on the evaluation of the analysis result provided by the analysis result provision unit 1520-4. For example, the model update unit 1520-5 may provide the analysis result provided by the analysis result provision unit 1520-4 to the model learning unit 1510-4 so that the model learning unit 1510-4 may ask for further learning or updating the model.

FIG. 22 is a diagram illustrating an embodiment in which the learning unit 1510 and the analysis unit 1520 are implemented in different devices.

Referring to FIG. 22 , an external server 200 may include the learning unit 1510, and the electronic apparatus 100 may include the analysis unit 1520. The electronic apparatus 100 and the server 200 may communicate with each other on the network.

The analysis result provision unit 1520-4 of the electronic apparatus 100 applies the data selected by the data selection unit 1520-3 to the model generated by the server 200 to obtain the analysis result. The analysis result provision unit 1520-4 of the electronic apparatus 100 may receive the model generated by the server 200 from the server 200, determine a user's intention in the user voice input through the microphone 130 using the received model, obtain object information from an image displayed on the display 110, or identify an object related to user voice in the image.

FIG. 23 is a block diagram illustrating a detailed configuration of the electronic apparatus 100 according to an embodiment.

Referring to FIG. 23 , the electronic apparatus 100 may include the display 110, the memory 120, the microphone 130, the processor 140, a touch sensor 150, a communicator 160, a global positioning system (GPS) receiver 170, a motion sensor 180, a button 190, a camera 192, and an audio outputter 194. Some of the configurations may be omitted, depending on the embodiment, and appropriate hardware/software configurations as would be apparent to those skilled in the art, although not shown, may be further included in the electronic apparatus 100.

The display 110 is configured to display an image. The display 110 may be the same as the display 110 of FIG. 2 . The display 110 may be implemented as a touch screen along with the touch sensor 150 capable of sensing a touch operation of a user.

The touch sensor 150 may sense a touch operation of a user or a pen. The touch sensor 150 includes a touch sensor, and the touch sensor may be implemented by electrostatic type or resistive type. The electrostatic type uses a dielectric coated on the surface of the display layer to sense micro electricity which is excited to the human body when a part of the body of the user is touched on the surface of the display layer, thereby calculating touch coordinates. The resistive type includes two electrode plates so that when a user touches a screen, upper and lower plates of the touched point are contacted to sense flow of current, thereby calculating touch coordinates. As described above, the touch sensor may be implemented in various types.

When the pen is used as an input means, if the pen is a pen including a coil therein, the touch sensor 150 may include a magnetic field detecting sensor capable of sensing a magnetic field changed by a coil inside the pen. Accordingly, the proximity operation, that is, hovering, may be detected as well as the touch operation.
